Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic lighting devices fail to simulate the realistic visual effect of flickering flames from candles or kerosene lamps, lacking the authentic appearance and interest of traditional lighting sources.
Innovation Solution
An electronic lighting device with a flame sheet and a swing mechanism, combined with a light-emitting element, where the light is projected onto the flame sheet to create a flickering effect, mimicking the movement of a candle or kerosene lamp flame, enhanced by a magnetic mechanism for random swaying and a specific emission angle for optimal visual impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If LED elements are disposed in a flame shell and controlled to flash on and off, then the visual experience of winkling and jumping light is improved, but the realism of simulating true flame is deteriorated
Solution Approach 1:
The patent uses a flame sheet that copies the visual appearance of a real flame, illuminated by LED elements. The flame sheet is made of translucent material with flame-like patterns that when lit from behind, creates a realistic flame appearance. This resolves the contradiction by using a visual copy rather than attempting to create actual flame movement with LEDs.
Solution Approach 2:
The flame sheet acts as an intermediary between the LED light source and the viewer. It transforms the static LED light into a dynamic-looking flame by using the translucent material with flame patterns, which diffuses and shapes the light to resemble real flame without requiring the LEDs themselves to move or change position.
2Manufacturing precision
If a swing mechanism is added to actuate the flame sheet to sway or swing, then the simulation of true fire is improved, but the device complexity is increased
Solution Approach 1:
The patent introduces a swing mechanism that dynamically moves the flame sheet back and forth to simulate the natural swaying motion of a real flame. The mechanism includes a rotating component that periodically displaces the flame sheet, creating realistic flame-like motion without requiring complex control systems.
Solution Approach 2:
The swing mechanism operates with periodic motion, rotating at controlled intervals to sway the flame sheet in a rhythm that mimics natural flame behavior. This periodic action is achieved through a simple rotating mechanism driven by a motor, avoiding the need for complex real-time control algorithms.
3Illumination intensity
If the light-emitting element is positioned to project light at an inclined upward direction through the through hole, then the visual effect is improved, but the device complexity is increased
Solution Approach 1:
The patent positions the LED light-emitting element at a specific location on the enclosure with a specific inclined upward orientation. This localized positioning ensures that light is projected through the flame sheet at the optimal angle to create realistic flame appearance, concentrating the visual effect in the critical area where the flame is viewed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a visually enhanced simulation of true fire, closely resembling the flickering flame of traditional candles or kerosene lamps, improving the aesthetic appeal and interest of electronic products.
Implementation Method 1
a light-emitting element installed on a sidewall of the enclosure such that an outgoing direction of a light from the light-emitting element is inclined upward and passing through the through hole of the enclosure, wherein the outgoing direction is intersected with a surface of the upper sheet, so that the light from the light-emitting element is projected on the surface of the upper sheet
Implementation Method 2
a swing mechanism disposed beneath the flame sheet, wherein the swing mechanism is configured to apply a force on the flame sheet to actuate the flame sheet to sway or swing
